Show HN: Track your HN post

I made the utility to help you track the rank of your hacker news post. Simply enter item id, or click "back" and select "History"->"View". Feedbacks are welcome.

Note: It only has two days of data, so older news won't work.

Very useful~ Thanks!

All the graphs have the same x-axis; how about combining them so you can see all the information at the same time in one screen without scrolling down?
